I applied through an employee referral. I was contacted by a Recruiting Manager the following day who wanted a quick rundown of my experiences to determine fit and if my skills were applicable to the role. He then outlined the positions and told me I would soon hear from a scheduler to setup my next interview. 1 week later, the scheduler connected me with a Director for a 30 minute phone interview. Nothing special... Asked for a summary of my experiences and the typical Why PwC questions. The call only lasted about 15 minutes. He expressed interest at the end of the call for a face-to-face. The scheduler contacted me the following Monday to setup three 30 minute interviews in Chicago with a Partner and 2 Directors. The Partner interview was very informal - questions were mostly about fit, experiences, and gave me an in-depth overview of the team, role and projects. The 2nd interview with a Director was very technical and dove deep into many item on my resume, tools used, approaches, techniques, etc. The 3rd interview was purely behavioral and focused on leadership questions.
